- dilation (lesson)
1) in a dilation of a figure, the distance between two consecutive vertices does not change
• true
• false
2) the coordinates of the vertices of a triangle JKL are J (4,8) K (8,8) L (4,2). Find the coordinates of the vertices of the image after a dilation by K = 0.25
• J (2,1) K (2,2) L (1,2)
• J (-2,1) K (4,2) L (1,0.5)
• J (1,2) K (2,2) L (1,0.5)
Answer:
see explanation
Step-by-step explanation:
(1) False
A dilatation enlarges or reduces the original figure
Then the distance between consecutive vertices changes.
(2)
Assuming the centre of dilatation is at the origin then multiply the coordinates of the points by the scale factor k = 0.25 ( a reduction )
J (4, 8 ) → J' (4(0.25), 8(0.25) ) → J' (1, 2 )
K (8, 8 ) → K' (8(0.25), 8(0.25) ) → K' (2, 2 )
L (4, 2 ) → L' (4(0.25), 2(0.25) ) → L' (1, 0.5 )
Arrange these numbers in order from least to greatest.

need help asap on 9, 10,and 11
Step-by-step explanation:
9. a)
2•(-2) = 2 - 6
-4 = -4
-2 -2 = -2•2
-4 = -4
Yes, the ordered pair is the solution
9. b)
-1 = 3•(-2) +5
-1 = -6 +5
-1 = -1
3•(-2) +(-1) = -2
-6 -1 = -2
-7 ≠ -2
No, the ordered pair is not the solution
10. (-1, -1) and (3, -1)
11.
y = 6 +x
Now substitute it in the first equation:
3•(6 +x) = 5x
18 + 3x = 5x
18 = 2x
x = 18/2
x = 9
Now, substitute x = 9 in the second equation:
y -9 = 6
y = 6 +9
y = 15

Write an equation of the line in slope intercept form for (0,3) and (4,2)
Answer: 13
Step-by-step explanation:
Step-by-step explanation:
the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.
x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).
so, the slope is -1/4.
the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3
so, the equation is
y = -1/4 x + 3

Write the measure in degrees (pi)/4
Let's see
[tex]\\ \rm\longmapsto \pi/4[/tex]
[tex]\\ \rm\longmapsto \dfrac{\pi}{4}\times \dfrac{180}{\pi}[/tex]
[tex]\\ \rm\longmapsto \dfrac{180}{4}[/tex]
[tex]\\ \rm\longmapsto 45°[/tex]
The solution is: the measure in degrees (pi)/4 is 45°.
Here, we have,
given that,
we have to find the measure in degrees (pi)/4.
now, we know that,
Measure of an Angle in Degrees = 180°
Measure of an Angle in Radians is:
180° × (π/180°) = π = 3.14 Rad
so, we have,
π/4
= π/4 × (180°/π)
=180 /4
=45°
Hence, the measure in degrees (pi)/4 is 45°.

find the y-intercept of the parabola y=x^2-5x+9/2
Answer:
To find the Y-intercept substitute in 0 for all the x's and solve for Y
Your answer would be (0,9/2)
Steps:
Y=0^2-5(0)+9/2
0^2 -5(0)=0
Y=9/2
0 is your x place
and 9/2 is your Y intercept
Answer:
y-intercept = 9/2 or 4.5
Step-by-step explanation:
In the given quadratic equation, y = x² - 5x + 9/2, where:
a = 1, b = -5, and c = 9/2
The y-intercept is the point at which the parabola crosses the y-axis, and occurs at point (0, c ). It is the value of y when x = 0. To find out what I mean by this, we can substitute the value of x = 0 into the quadratic equation:
y = x² - 5x + 9/2
y = (0)² - 5(0) + 9/2
y = 0 - 0 + 9/2
y = 9/2
Therefore, the y-intercept (c) = 9/2, and has coordinates, (0, 9/2) or (0, 4.5).
Attached is a screenshot of the graph, where it shows the y-intercept.

What is the equation of the line that passes through the point (–2, 1) and
has a slope of - 5/2
Answer:
y = -5/2x + -4 (or) y = -5/2x - 4
Step-by-step explanation:
Your slope is -5/2, so all you have to do is take the point (-2, 1) and use the slope to find a second point of (0, -4) which is coincidentally the y-intercept. Then you just plug the data into the equation y = mx+b. You do that and you get the answer of y = -5/2x+-4

2.5% of 2 2/5
is what number?
Answer:
The number is 0.06, or 6 hundredths.
Step-by-step explanation:
If we convert 2 2/5 to a decimal, we get 2.4
Then, we can convert our percentage to a decimal by moving our digits two units down, giving us .025.
Now, we can multiply 2.4 and .025, which gives us 0.06
